1. A Change in the Quantity of Grease Consumed Maintenance departments track their grease consumption to monitor and control costs. A change in consumption is a sure sign that your lubrication program is on the right track. Most organizations are guilty of over-lubricating. Expect lower grease consumption as your program matures. Bad procedures lead to […]

A proven method to assess gearbox condition is to collect a DYNAMIC ultrasound signal. If possible, you want to capture at least 3-5 revolutions of the gearbox. From there, analysis is straightforward. Use Ultranalysis (UAS2) software to view the signal in the time waveform and spectrum displays. Use the software’s many analysis tools to determine […]

Comments Off on Where Should I Place My Ultrasound Sensor on a Gearbox?

With the proliferation of online monitoring systems utilizing permanently mounted sensors, users will need to beware of “direction sensitive” vibration and possible sudden unexpected failure due to insufficient data. The thought of insufficient data may seem incredible when thinking of constantly monitored equipment, but consider the all too common (imho) practice of uni-directional (one direction) […]

Comments Off on Is Your Vibration Analysis Pointed in the Right Direction?

While the person in charge of collecting vibration data is actually collecting the data, they should watch the data “live” for unusually high amplitudes or discontinuities in the data. This will not increase the data collection time, and if any of these issues are detected, the person can evaluate whether or not the data is […]

♫ And it’s too late baby now, it’s too late; though we really did try to make it. Something inside has died and I can’t hide and I just can’t fake it…♫ So go some of the lines of the old Carole King hit from 1971. Unfortunately, that pretty well sums up the situation for […]
